Water wicks up the gap between shingles and drip edge on a flat roof, causing rust and sheathing rot, and the homeowner is unsure which sealant product to use without making a mess.

Existing sealants (Flex seal, Lap seal) are messy to apply and may drip, while Eternabond tape may look bad; no easy, clean, durable solution specifically for sealing the drip edge-to-shingle interface.
